The death was reported Monday night in a statement by Scott Coker, president of Slice's promotion company Bellator.

"We are all shocked and saddened by the devastating and untimely loss of Kimbo Slice, a beloved member of the Bellator family," Coker said in the statement.

"One of the most popular MMA fighters ever, Kimbo was a charismatic, larger-than-life personality that transcended the sport," he added.

Slice, whose birth name was Kevin Ferguson, had been admitted to a hospital near his home in Coral Springs, Florida, for undisclosed reasons on Monday, a police spokeswoman confirmed to ESPN. His condition was "dire," according to TMZ.

The death is being handled as a medical incident, and no foul play is suspected, the spokeswoman told Yahoo Sports.

Slice gained fame in 2003 after videos of his brawling in unsanctioned street fights spread across the internet.

He parlayed his fame into successful careers in mixed martial arts and boxing. He last competed in an MMA bout in Houston in February.
